Abstract

PURPOSE:To simply check performance of a gas leakage alarm device by supplying a fixed quantity of test gas into an outer interuption hood to detect the quantity of supply thereof by a transit quantity of slider of a variable resistor. CONSTITUTION:An air cylinder type of gas injection container 1 is set in a body 9 conforming to a hollow thereof. Thereby in the injection container 1 inflammable gas, for example isobutane 100% gas, is put. The revolution of a motor 5 is transferred to a gearshaft 4 through a reduction gear 6. As the gearshaft 4 is fixed through the body 9 at both ends, by pushing the shaft 2 in the injection container 1 a fixed quantity of flow of gas flows in an outer interruption hood. Said quantity of flowing-in can be taken out as electric signals by connecting a sliding type of variable resistor 8, which makes resistance variation according to traveling thereof, with the shaft 4.
